mac: ignore resource fork when checking file sizes Some evil evil awful tool adds resource forks to files it's comparing. Our Mac-specific code to do bulk stats was accidentally using "total size" which includes those forks in the file size, causing them to be reported as modified. This changes it to only care about the normal data size and thus agree with what Mercurial's expecting.

copies: fix detection of divergent directory renames If we move all the files out of one directory, but into two different directories, we should not consider it a directory rename. The detection of this case was broken.
